The seal of the invention is applicable to the type of bottle caps that are formed by a capsule (3), in such a way that the seal itself is a ring (1) connected to the bottom edge of the capsule, in order to remain located underneath an annular projection which the bottle neck has for this effect, in such a way that in the coupling of the unit (capsule-seal) upon the bottle neck alluded to there is no breakage, while in the operation of unscrewing the capsule, upon the ring (1) of the seal coming up against the annular projection of the bottle neck, the tearing of the connecting means between the ring (1) and the capsule (3) is produced. The connecting means between sealing ring (1) and capsule (3) are formed by means of a series of tearable appendixes (4) and by another series of oversized appendixes (5), the latter grouped in a sector of approximately 90.degree. and located as of a transversal weakening (6) starting the tearing. The oversized projections or appendixes (5) form permanent connecting means of the ring (1) of the capsule (3), even after unsealing or untearing the appendixes (4.)
